The -k option to telnet supposedly allows one to specify the Kerberos
realm of a remote host, bypassing krb_realmofhost(). It doesn't work on
any platform other than Ultrix. This is not a show-stopper bug, but
fixing it would be nice.
I have reviewed his patch and it is correct. The fix does not affect
any code outside what appears in the patch.

Hi...
I'd like to report a bug in the file /mit/telnet/src/telnet/telnet/main.c
Currently, the extern variable "dst_realm_sz" is defined as a char, when in
fact it is defined as an int in /mit/telnet/src/telnet/libtelnet/kerberos.c.
This causes the "-k" option to fail on this SunOS 4.1.3, and possibly on
other platforms (because the strncpy() copies zero bytes). Following is a
patch to correct this bug.
